Technicians from the IHS Public Health
Laboratory organized laboratory set up in camps near primary
schools, set up for base line survey of health status of school
children.
These camp public health laboratories will do quantitative
tests to estimate parasite load in stool samples collected from
school children. Hookworm is usually a major contributor to
anaemia and easy fatiguability among school children, and is
likely to affect school attendance as well as learning. Most
research studies to estimate prevalence of soil transmitted
helminthiasis including hook worm, do qualitative tests that
determine whether evidence of parasite infestation
is there or not. But mere presence of parasite infestation does
not necessarily lead to anaemia or fatiguability. The quantity of
worm load in children is a key factor for the adverse outcome of
aneamia, easy fatiguability, and poor learning outcomes. Hence
quantitative estimation of parasite load in stool samples is very
important. However the logistics of such testing programmes is
usually very difficult.
On 13th and 14th August, 09 technicians from
the IHS Public Health Laboratory were trained by the Microbiology
department of the Nizams Institute of Medical Sciences (NIMS), in
the Kato Katz technique of quantitative estimation of parasite
load in stool samples, under the leadership of Dr. V. Lakshmi.
Subsequently the IHS Camp Lab team went to
two primary schools and camped there from 21-22 Aug, 09. The Camp
Lab team was accompanied by Mrs Padmashree, Senior Technician,
Microbiology, NIMS, who was deputed by Dr. Lakshmi, the Head, Dept
of Microbiology. Temporary lab was set up in one of the village, in
a room provided by Panchayat President.
The Camp Lab team screened 59 samples from 2
schools. Analysis was done by IHS technicians under the guidence
of the Senior technician from NIMS. Out of 59 stool samples, only one sample was positive for Hookworm. The picture of Hookworm egg

The Camp Lab team will start formal data
collection activity from 24-08-09 and it is expected to
get completed by September 15 2009.
This activity is part of the base line survey
of school children’s health status, which is part of an action
research programme by the Azim Premji Foundation to improve
primary education performance. The study is a 3 way partnership
between Andhra Pradesh Government, Azim Premji Foundation and The
Institute of Health Systems with support from the World Bank. The
main objective of the study is to measure the health status of
primary school children in study and control schools, prior to
implementation of the interventions. The indicators chosen to
estimate health status include anthropometric measures of child
nutritional status, a simple physical examination for vision and
Vitamin A deficiencies, a pin prick blood test for haemoglobin
count, and a stool test for prevalence of worms.
